def close_incoming
  __builtin_cexpr! %q{
    ractor_close_incoming(ec, RACTOR_PTR(self));
  }
end

Closes the incoming port and returns whether it was already closed. All further attempts to Ractor.receive in the ractor, and send to the ractor will fail with Ractor::ClosedError.

Example

r = Ractor.new {sleep(500)}
r.close_incoming  #=> false
r.close_incoming  #=> true
r.send('test')
# Ractor::ClosedError (The incoming-port is already closed)
